Come join Bob Costas in his Fortress of Solitude

Bob Costas introduced Saturday night's NBC Olympic coverage by noting that his icy studio bore a striking resemblance to the classic "Fortress of Solitude," the North Pole lair where Superman would hide out to keep from having to save every cat stuck in every tree on the planet.

"Unfortunately for me," Costas continued, "the eye infection is not getting any better, so for the time being I’m still stuck with Clark Kent’s glasses."
